BOTTLE STOPPER.

Application filed August 16, 192 4. Serial No. 732,361.

This invention relates to a det rice for use in connection with bottles having closures of the well-known crown cap or seal type. A 'closure'of this type comprises a cap having a disk of cork or other packing material for sealing the mouth of the bottle,

and a crimpcd flange for engaging a bead formed on the bottle neck and surrounding said month. As is well known, such closures cannot be readily removed without a special appliance, and after having been removed cannot be replaced so as to seal the bottle securely. The present invention has for its general object to provide a simple and inexpensive appliance for removing closures of this type as well as for temporarily closing and sealing the mouth'of the bottle after the original closure has been removed. The more particular objects of the invention, together with means whereby the latter maybe carried into effect, will best be understood by the following description of a preferred embodiment thereof illustrated in the accompanying drawings, in

which:

Fig. 1 is a plan view of the blank from which the device embodying the invention is formed.

Fig. 2 is a side elevation of the blank 9 after being bent and shaped to form the device.

Fig. 3 is a detail section taken substantially on line 33, Fig. 2.

Figs. 4 and 5 are side elevations taken substantially at right angles to one another, showing the application of the device to a bottle.

Fig. 6 is a plan view of the bottle with the closure applied thereto.

49 As shown, the device or appliance embodying the invention comprises a body composed of resilient sheet aterial, preferably sheet metal, and formec from a blank of substantially the shape shown in Fig. 1

which may be stamped or died out from the sheet metal stock in accordance with the usual. well-known die stamping process. Said body comprises a closure portion 15 having at its lateral edges segmental ex tensions 16 which are bent to fortn flanges adapted to retain, in permanently assembled relationship with said closure portion, a capor gasket 17 composed of rubber or other suitable packing material adapted to loops.

fit tightly'over the mouth ofthe bottle .B,

are bent to form upwardly. and outwardly inclined spring loops 20, thereby forming of the extensions 18 spring fingers connected with the closure portion 15 by said spring 18 are bent inwardly into parallel positions so as to engage under the bead or flange. b of the bottle neck at spaced points. The extension forming one of the spring fingers 18 is projected beyond the lugs 19, as shown at 21,. and is shaped, as shown at 22, to

constitute a crown seal remover or bottle opener of well-known type.

In operation, the end 22 of the projection 21 is employed to remove the crown seal from the bottle to be opened. When it is desired to close the bottle again, the lugs 19 of the spring finger 18 opposite the projection 21 are engaged under the bead b of the bottle neck, as shown in dotted lines in Fig. 4, after which, by pressure of the thumb upon the closure portion 15, the lugs 19 of the other spring finger are caused to snap into position beneath said bead, as shown in full lines in said figure, thereby firmly seating the cap or gasket 17 upon the mouth ofthe bottle and sealing the latter. It will be noted that the lugs 19, by reason of their triangular form, react upon the bead 7) with a cam action, thereby spreading the spring fingers and facilitating the application of the device. It will also be seen that, when the closure is in place. and by reason of the upwardly and outwardly inclined position of the spring loops 20, the pressure exerted by said loops upon the lugs 19 has an upward component tending to seat the cap or gasket 17 upon the mouth of the bottle with considerable firmness. It will further be seen that the pointed ends of the lugs 19 are firmly engaged with the under or inner side of the head 7), and that, by reason of the fact that said lugs engage said bend at four spaced or separated points, the closure is securely The lugs 19 of each spring finger retained on the bottle. It is found in pracim ties that, by reason of the construction deit is calle' upon to withstand. Said devicescribed, the device is held in placewith greater firmness and security than in any against an pressure which, in ordinary use;

' 1 may, nevertheless, be easily removed at any tice'without departure from the spi 't and defined y the one of said last named extensions being prodisen aging the lugs l9- at devic from the bead b.' p v -tx-lt'willbe obvious that the particular embodiment'of the invention above described is following claims.
